What time do all milk teeth fall out. What milk teeth fall out in children: a diagram

All parents go through a period when their baby's teeth change. It can hardly be called the most pleasant for moms and dads. This is mainly due to feelings for your child.

However, most children endure their shift without any problems. Many are even waiting for this event, discussing with friends, they always know which and who has dropped out, how much milk is left. Often this is influenced by stories about a tooth mouse or a fairy who must bring something in exchange for a lost tooth.

Despite this, adults should be aware of many nuances, in particular, the timing and order of falling out, as well as the basic rules of hygiene and oral care at this undoubtedly important time. In addition, sometimes the deadlines are violated, so you need to know about the causes of this phenomenon.

Why is this happening?

Naturally, The reason for the loss of milk teeth is simple - it is necessary to make room for permanent teeth. with which a person will live for the rest of the time. However, the question naturally arises why this change is needed at all and why those who are called permanent do not immediately grow.

To answer it, you need to know a little anatomy and physiology. The fact is that by the time when the baby does not have enough milk alone and he begins to eat more solid food (and this happens quite early - from about six months to 9 months), the jaw is still very small. Gradually, it begins to grow, interdental spaces increase.

Under dairy, the rudiments of permanent ones begin to gradually form. When they become active and begin to grow, the roots of milk teeth dissolve and they gradually fall out.

Useful information

Before talking about the timing and order of loss, you need to talk a little about the milk teeth themselves. Since they have quite a few features, including when they fall out.

• A complete set of them in a baby is 20 pieces - 5 on each side on both jaws.
• Their names are as follows, starting from the center - the central and lateral incisor, canine, first and second molars. The order is the same for both the upper and lower jaws.
• Despite the fact that constants are often called indigenous, this is not entirely true. After all, dairy plants have roots in the same way. Only they are shorter.
• There are differences not only in the roots, but also in general in the structure. The temporary ones are shorter, bluish-white instead of yellowish like the permanent ones, and have enamel that is almost twice as thin.
• Under them, from the very birth, the rudiments begin to develop. permanent teeth. When the time comes, they begin to grow slowly, which leads to the gradual resorption of the roots.
• The smaller the root becomes, the more the crown begins to loosen, since there is simply nothing to hold it with.

• One of essential functions temporary teeth, except, of course, straight, is signal. That is, they indicate to the constants in which place they should grow.
• If, due to caries or trauma, one of them had to be removed much ahead of time, then the permanent one may not cut through correctly. It is also associated with root resorption. It is in this empty gap that a new one will begin to erupt.

Scheme

If parents remember in what order the first teeth were cut, then it will not be a problem for them to determine the order in which they fell out. They are about the same. But in order to clearly imagine this, you need to talk in more detail about each of them in relation to the others.

The process of loss, as well as growth, occurs symmetrically. That is, at about the same time, identical teeth begin to loosen on both sides of the jaw. It should also be noted that sometimes the child may not experience loosening.

Then the prolapse will still be in the correct order, but it will be sudden both for the child himself and for the parents.

Approximate scheme

To begin with, we will answer not the question “when”, but “in what order”:

• The process in most cases starts from the bottom. After that it is repeated on upper jaw.

1. Mandible - central incisors.
2. Upper - central incisors.
3. Then the lower lateral incisors.
4. The upper incisors are lateral.

• After the incisors fall out, the order of "liberation" of the jaws changes.

1. Upper small (or first) molars.
2. First molars from below.
3. Upper fangs.
4. Fangs from below.

• The last stage occurs in the same way as the first - from the bottom up.

1. Large (or second) lower molars.
2. Upper large molars.

The process of changing

Sometimes moms and dads are interested in whether all the first teeth will change. It is difficult to answer it unambiguously. The answer will depend only on how you approach the problem.

First of all, it's a matter of wording. After all, the “firsts” are not always “dairy”. If you answer the question, will all dairy products fall out, then the answer is yes. All twenty pieces. However, there is another aspect that is almost never taken into account by worried parents.

Among mothers, fathers, grandparents, there is an almost universally widespread opinion that the change of teeth begins with loosening and loss of milk teeth. However, this is not entirely true. The fact is that by the age of four or five, the jaw grows quite strongly. Therefore, there is enough space on it for the growth of additional ones.

The number of permanent teeth is 32 pieces. Among them there are 4 wisdom teeth or third molars. If you do not count them, there are 28. Divide the "extra" eight by 4 (jaws and sides), we get 2 additional in each of their jaw quarters. They are called premolars, and they are not part of the dairy. Exactly with the growth of a pair of premolars and the replacement process begins.

Timing

Speaking of timing, it should be noted that can only be named the approximate time . This happens because all the processes of development and growth in children depend on the individual characteristics of the body. So, what time do milk teeth fall out?

The average age when the first milk teeth begin to loosen is about 5-6 years. However, even if the process begins at 4 years old or at 8 years old, you should not panic. After all, there can be quite a few reasons for accelerating this or, conversely, delaying it.

However, if at the age of four the baby came to you and said that his teeth were loose, it is better to take the time and go to an appointment with pediatric dentist. After all, the child could hit and damage the root, or caries began, which can also cause the loss of milk teeth.

These factors must be excluded. After all, too early loss of temporary teeth for unnatural reasons can lead to the fact that the permanent ones lose their kind of “landmark” and grow crookedly.

By the age of about 12-13 years, everything ends. In relation to the timing of the end of the process, you can apply the same rule as for the start. One or two years doesn't really matter.

Reasons for changing dates

If the delay is too long, then you can add not so harmless factors. For example, it can be various endocrine abnormalities and developmental disorders that have not been noticed by doctors before.

In addition, rickets or chronic infectious disease almost unrevealed.

Front change

As can be seen from exemplary scheme located above, it is the front temporary teeth that begin to stagger and fall out first. These include 8 pieces, four on each jaw.

These are, first of all, the central incisors, which will first fall out from below, and then from above. Age (again approximate) - 6-7 years. But they begin to gradually loosen on average after the fifth year of life, and this process lasts about two years. I.e four central teeth should fall out in a year.

Next in line are the lateral incisors. As in the case of the central ones, the lower ones go first, then the upper ones. This happens at 7-8 years old. About 6 years old, the roots begin to dissolve, which leads to their loosening for up to 2 years.

Indigenous change

All the remaining 12 milk teeth can be conditionally called molars. They begin to change immediately after the front ones.

• After the seventh year, they begin to stagger, and then by the age of eight or ten, the first molars fall out from above. They are located immediately behind the fangs.
• Then comes the turn of the lower first molars. This happens almost simultaneously with the top. Loosening here is longer - for about 3 years.
• A year later, the upper fangs are replaced - at the age of nine - eleven.
• They are followed by the lower fangs in the same period. As in the case of molars, canines become loose at about three years old, and this process begins after eight.
• The second lower molars follow the loss of fangs - at 11-13 years.
• The last teeth to fall out are usually the upper teeth, the second molars. It will also be around 11 or 13 years old.

What do we have to do?

When a milk tooth falls out, there is no need to worry too much. However, you need to know a few rules that are intended for both the children themselves and adults.

• Refrain from eating for 2-3 hours.
• Remove too aggressive dishes and foods from the child’s diet - sour, spicy, salty.
• If the wound bleeds, close it with a small cotton swab for a few minutes.
• You can not constantly touch the wound with your tongue and even more so with your hands. Thus, you can accidentally bring the infection.
• If there is pain or itching, then you can use special gels, but it is better to consult a dentist.

The average is considered when the last milk tooth falls out by the age of fourteen. Therefore, the whole process of changing temporary to permanent ones can take about 10 years.

In all children, milk teeth after a certain time change to permanent ones. Most children endure this period without any problems. Although parents are usually ready to change their children's teeth, sometimes unforeseen situations occur when they fall out earlier or later than the expected date. This may be accompanied by inflammation in the mouth, and new teeth often erupt with a curvature. In this case, you should not postpone a visit to the dentist. So when do baby teeth fall out? Let's try to figure it out.

general information

Changing teeth is a natural process. The main cause of prolapse is the preparation of a place in the oral cavity for permanent painters. They will remain for life. So why permanent teeth appear not immediately, but after dairy?

The first teeth erupt at about 6 months. At this age, the baby begins to be fed not only milk, but also more solid food. But the jaw of the baby is still very small and cannot accommodate a complete set of teeth. Along with the growth of the child, his jaw begins to increase in size. Between the milk teeth, the gaps begin to increase, and the load on these teeth also increases.

In a child aged 6-7 years the foundation is laid for the growth of permanent teeth. There is a gradual resorption of the milk roots, as a result of which the teeth begin to stagger and fall out, unable to stay in the hole.

Scheme of changing teeth

At what age do milk teeth fall out? This period begins at the age of 6, and the formation of constants usually ends at 13-14 years. The change of teeth occurs symmetrically, that is, from the left and right sides jaws teeth of the same type fall out. Most often, the lower central incisors fall out first, and only then the lateral ones. On the upper jaw, the teeth are replaced much later.

Milk teeth in children - loss pattern:

The period of loss of milk teeth is 5 - 8 years. Many factors influence this:

• diet;
• heredity;
• Availability chronic diseases;
• transferred infections;
• maternal toxicosis during pregnancy;
• gender of the child.

Symptoms

When baby teeth start to fall out the following symptoms may be observed:

• increased space between teeth;
• violation of the chair;
• an increase in body temperature up to 38 degrees (sometimes);
• swelling of the gums, which may be accompanied by painful sensations;
• resorption of milk roots.

In some cases, the permanent tooth grows next to the milk tooth and cannot push it out. In such situation milk tooth should be removed to make room for the permanent one.

oral care

When baby teeth start to fall out, oral care should be taken. The teeth that have appeared are not yet too strong, since the protective layer is not fully formed, so it is recommended to brush them twice a day. Children usually do not like different hygiene procedures. They should be taught to use a toothbrush regularly, explaining the importance of cleanliness in the oral cavity.

Another important procedure during the period of loss is the sanitation of the oral cavity. Milk teeth may show signs of caries, which can spread to permanent ones. And since the enamel of the "young" teeth is still very weak, they are highly susceptible to damage.

When milk teeth fall out, the gums become loose and the child does not feel pain. But in some cases, the baby feels pain. To anesthetize the gums and normalize the microflora, the following agents are used:

• Kamistad;
• Solcoseryl;
• Dentokind;
• Kalgel.

After tooth loss the child should not eat for two hours. Until the wound heals, it is necessary to refuse salty, spicy and very hot dishes. It is best to feed the baby with cereals and soups. The mouth should then be rinsed gently. It is forbidden to get rid of the remains of gore, because they will fall out on their own in a few days.

The child may sometimes have a fever. If he is fine, then there is nothing to worry about. But if, in addition to temperature, other signs of malaise are observed, then this already indicates an inflammatory process. The child must be shown to the dentist.

When permanent teeth begin to appear, parents must control whether they grow correctly. If signs of displacement appear, the child should be taken to an orthodontist. During the growth of permanent teeth, you can help them take correct position. In addition, the baby during this period must eat properly in order to get the vitamins and minerals necessary for teeth. . Very useful:

Causes of very early or too late loss of milk teeth

Milk teeth affect the future location of permanent teeth. Therefore, it is extremely important to save the first teeth until the permanent ones appear. At the place of loss, a free space appears, to which neighboring teeth begin to gradually shift. By the time the molar begins to grow, it will no longer have enough space, and it will grow crooked. To eliminate the defect of the dentition, you should consult an orthodontist. With the help of a special plate, the displacement of the dentition is prevented.

The following reasons lead to early loss of milk teeth:

• malocclusion;
• trauma;
• forced removal due to infection;
• extrusion by adjacent teeth.

Dropping out late happens due to:

• rickets in early age;
• genetic predisposition;
• the presence of severe infections or phenylketonuria in history.

According to dentists, the late loss of milk teeth is much better than the early one.

Possible problems and solutions

Sometimes with the loss of milk teeth in children and the eruption of permanent teeth, various problems arise.

shark teeth. Such a pathology is diagnosed when the permanent teeth grow before the milk teeth fall out. As a result, they are arranged in two rows parallel to each other. According to practice, such a violation does not affect the subsequent development in any way. maxillofacial apparatus. This pathology is observed for three months, after which the milk teeth are removed.

Excessive soreness. Sometimes when teeth fall out, pain occurs, the gums swell, and body temperature rises. It usually does not rise above 38 degrees, but since there is a load on nervous system, then the baby quickly gets tired and he has insomnia. In addition, sore gums can lead to loose stools. In order to get rid of unpleasant symptoms, the doctor prescribes the drug Dentokind. It relieves inflammation and pain, normalizes sleep, restores the nervous system.

The appearance of a hematoma which gives the child severe discomfort. The formation of a hematoma occurs at the edge of the gingival fold and is a cyanotic or purple-red vesicle filled with bloody fluid. The hematoma is very painful, because of which the child cannot eat normally, he begins to act up. Usually the hematoma goes away after a few weeks, when the permanent tooth begins to erupt. To alleviate the child's condition, Solcoseryl adhesive dental paste is used, which must be lubricated with an inflamed area. Well reduce pain dental gels Kalgel or Kamistad.

Thus, when baby teeth begin to fall out in children, it usually does not cause them any discomfort. Many parents are interested in the question: at what age does this happen and will there be any problems? This happens differently for all children, and if problems arise, then you should definitely contact the dentist.

The first set of teeth in humans, as in most mammals, is temporary and is called milk teeth. Their service life in the formed state is small. Milk teeth erupt after birth. The change of milk teeth to molars begins at the age of five or six and ends completely by the age of twelve or fifteen.

By the age of five, milk teeth are gradually moving apart. This means preparing the maxillofacial apparatus for the change of teeth.

If the gaps between the teeth in a child do not increase, it should be shown to an orthopedic specialist. Otherwise, due to lack of space, fangs may begin to grow inward. oral cavity or horizontally, through the lateral surface of the gums.

The appearance of permanent teeth is preceded by physiological process during which the roots of milk teeth are resorbed. The rudiments of permanent teeth are located between the roots of the milk teeth, so the resorption of the latter begins from the surface adjacent to the rudiment of the permanent tooth.

Resorption goes from the top of the root to its base, and the tooth gradually begins to stagger. When the process affects the neck of the tooth, it falls out.

Does everyone change?

The child has 20 milk teeth. In an adult, the number of teeth can vary from 28 to 32. What milk teeth fall out? Everything! Normally, by the age of 14 they should be replaced by permanent ones. Some teeth initially erupt as permanent teeth.

Procedure and terms of change

Simultaneously with the loss of milk teeth, the eruption of permanent teeth occurs. For the process of changing teeth, it is important which ones fall out first.

The order of loss corresponds to the order of appearance of milk teeth - first the incisors change, then the first and second premolars, the last change is the canines.

The first molars grow permanent until the teeth change. The second molars appear in empty spaces formed during the growth of the jaw. Third molars (wisdom teeth) have lost their functionality and in many people do not grow at all.

Factors affecting the order and timing of the change of teeth:

• child's genotype
• duration of breastfeeding
• the presence of toxicosis in the mother during pregnancy,
• infectious diseases carried by the child.

Approximate terms of eruption of permanent teeth:

1. 6–7 years - the first molars (appear immediately permanent);
2. 6–8 years - central incisors;
3. 7–9 years - lateral incisors;
4. 10–12 years old - first and second premolars;
5. 9–12 years - fangs;
6. 11–13 years - second molars;
7. 17–25 years - third molars, or "wisdom teeth".

Milk teeth begin to loosen around the age of five.

Significant deviations in the timing of teething are an indirect symptom of a developmental disorder.

Too early eruption may indicate endocrine disorders and, conversely, a delay indicates a metabolic disorder, possible rickets, chronic infections etc.

Fine

There is an approximate fallout schedule:

1. 6–7 years - first the lower, then the upper central incisors;
2. 7–8 years - lateral incisors;
3. 8–10 years - first molars;
4. 9–11 years - fangs;
5. 11–13 years - second molars.

The timing of the loss of milk teeth is individual. For some, they may start a little earlier, for others - a little later. It depends on many factors. Baby teeth falling out between the ages of four and eight is normal.

Very important correct order fallout.

In pediatric dentistry, there is such a thing as spatial balance. Milk teeth determine the location of the molars, their spatial arrangement in the mouth. Preservation of milk teeth until the moment when they should fall out maintains the spatial balance in the oral cavity.

Too early or, conversely, too late tooth loss can lead to eruption disorders.

Too early

early dropout baby tooth can happen due to:

• injury,
• a growing tumor
• too much strong pressure adjacent teeth,
• abnormally deep bite
• forced tooth extraction.

This disrupts the spatial balance in the mouth - adjacent teeth move, trying to occupy the vacated space. Eruption of a permanent tooth is difficult and, as a result, it grows uneven.

"Crooked teeth" distort facial features, can cause unnatural facial expressions and pronunciation defects. This develops complexes in the child, prevents him from "joining" the children's team.

To avoid not proper development of the dentoalveolar system, the orthodontist installs a space retainer - a special device-plate.

Too late

The change of teeth is in direct proportion to the timing of teething in infants.

The delay in dropout can be caused by:

• transmitted infection,
• chronic dyspepsia,
• phenylketonuria,
• rickets,
• hereditary predisposition.

It is generally accepted that the physiological delay in the loss of milk teeth makes the permanent ones more resistant to caries. However, if by the age of eight the child's milk teeth have not begun to stagger and fall out, it can be assumed that there are no rudiments of permanent teeth.

It happens that milk teeth stagger, but they are in no hurry to fall out. Permanent ones grow next to them and, since they do not have enough space, they grow at random, often protruding from the dentition. Timely consultation of the orthodontist and correction of the dentition will help to solve the problem.

The length of the fallout period

From the moment when the first milk tooth falls out to the time when the last ones fall out, five to eight years pass.

Minor fluctuations can be caused by:

• diet,
• quality and chemical composition drinking water,
• genetic factor.

Normally, the last milk tooth should fall out by the age of 14.

Problems that arise

Changing teeth is a physiological process. However, parents may face a number of problems.

The main ones are:

• "shark teeth"
• severe pain and discomfort
• A new one does not grow in place of a lost tooth.

We will consider these problems in more detail.

In the process of resorption of the roots, the milk teeth loosen and, pushed out by the growing permanent teeth, fall out. But sometimes the mechanism of this process fails. The permanent tooth has time to grow before the previous milk tooth falls out.

Sometimes a number of such permanent teeth grow parallel to a number of milk teeth, which, it is not clear why, do not fall out. Such teeth are usually called "shark teeth", by analogy with the dentition of sharks, in which the teeth grow in three rows.

Studies have confirmed that "shark teeth" do not cause problems in the long term. When a baby tooth falls out, the “shark tooth” begins to move and takes its normal place.

However, if the loss does not occur within three months after the appearance of a permanent one, then a dentist consultation is necessary.

Severe pain and discomfort

Sometimes the loss of milk teeth in children is accompanied by severe pain, swelling of the gums, and the temperature may rise. An increase to 38°C is physiological.

All this can cause stress on the nervous system. Unlike older children, babies in the first years of life have fatigue and exhaustion. nerve functions comes much faster.

Inflammatory processes of the gums cause fever, cause diarrhea and prevent the child from falling asleep.

Conventional drugs have only analgesic, or anti-inflammatory effect. Therefore, doctors usually recommend specially designed for babies. Dentokind, which, in addition to analgesic and anti-inflammatory effects, calms the nervous system and stabilizes sleep.

Occasionally, a hematoma is formed on the edge of the gingival fold - a bubble of purple-red or cyanotic color. When punctured, a bloody fluid comes out. After a couple of weeks, a tooth erupts at the site of the hematoma.

Can be lubricated sore gums dental adhesive paste Solcoseryl. Severe soreness is removed with dental gels based on lidocaine - Kalgel, Kamistad.

Attention! If you are allergic to lidocaine, anaphylactic shock is possible!

At severe pain, the appearance of a hematoma or a significant increase in temperature, it is necessary to urgently contact a pediatric dentist.

A new tooth does not grow in place of a lost tooth

The absence of teeth in permanent occlusion can be caused by two reasons.

1. retention. Eruption delay. Partial retention is said to be when top part the crowns erupted, and the lower one remained hidden under the gum. If the tooth is formed, is in the jaw, but does not erupt, such a retention is called complete. Causes of retention: premature removal of a milk tooth, a delay in its loss, the germ is located incorrectly or too deep.
2. Adentia. Absence of a tooth. When one or more teeth are missing in the dentition, this is considered partial edentulous. The reason is the death of the germ of a permanent tooth. Complete adentia is the result of a violation prenatal development fetus and is extremely rare.

Both retention and adentia require an immediate consultation with an orthodontist

Every parent wants their child's teeth to be healthy.

What is needed for this?

• From the age of two, teach your child to brush their teeth daily. Toothbrush should fit the child in size, have soft bristles with rounded tips. Only children's toothpaste should be used - it is safe to swallow and hypoallergenic.
• Every time after eating, it is useful to rinse your mouth with water. This will protect the molars from the development of caries.
• The enamel of an erupted tooth is not mineralized enough at first. The diet of the child should be complete, with a predominance of foods rich in calcium.
• When a tooth falls out, a bleeding wound may remain. Make a swab out of sterile cotton and let your child bite on it.
• If there is an inflammatory process in the milk tooth, if the child feels discomfort from a loose tooth, if you are in doubt whether all the milk teeth fall out in your child on time, consult a doctor.

Folk omens

At different peoples there are signs and superstitions associated with fallen milk teeth.

For example, in Yorkshire it was believed that a tooth should be thrown into the hearth, accompanying the ceremony with a certain proverb. If this is not done, then after death a person will be doomed to search for him forever.

In Sussex, a fallen tooth was also burned, but for a different reason. It was assumed that if any animal found and ate it, the child's new teeth would grow like those of that animal.

The vast majority of nationalities were afraid that a witch, finding a fallen tooth, could harm its owner.

Where to put a lost milk tooth?

The custom of throwing out teeth belongs to many Slavic peoples. For example, a child is asked to leave right hand through left shoulder, saying at the same time: “Mouse, mouse, you have a milk tooth, give me a bone instead!”

A more modern (and pleasant) custom is to give the tooth to the Tooth Fairy. This is fairy tale character, coined by the Spanish writer Luis Coloma. Before going to bed, a child puts a tooth under the pillow, and when he wakes up in the morning, he finds a coin or a gift instead. What is the meaning of this ritual? Financial compensation for the child's pain and trouble.

Frequently asked Questions

Consider the most frequently asked questions by parents.

Do baby teeth have roots?

There is! But by the time they fall out, they gradually resolve, the tooth, losing its support, begins to stagger and falls out already without a root. This created the erroneous opinion that only permanent teeth are molars.

Photo: A lost milk tooth has no root

What to do if a tooth fell out prematurely?

Consult an orthodontist. He may recommend the use of a retainer, a structure that holds adjacent teeth in place. This is necessary in order to ensure the proper development and growth of permanent teeth.

Waiting for the eruption of the first teeth in babies for parents is always an extremely exciting process and associated with a lot of questions: when the first tooth will already appear, whether it will be unpleasant for the child during eruption, or how many milk teeth a child should have in general and when they all will appear.

Naturally, parents want to help their children survive this difficult period of the appearance of milk teeth in children, and sometimes they have more questions than answers, in particular, about the number of milk teeth in children. Today we will tell you what are milk teeth in babies, how many milk teeth children should have in total and when they should erupt.

The concept of milk teeth and how they look

Milk teeth are called the first teeth, which eventually fall out and are replaced by permanent ones, starting at about the age of six. At about six months teething process begins and completed by the age of three. Growth and shedding usually coincides with the schedule, sometimes there are slight deviations, but this is normal. If the milk tooth erupts earlier or much later than the schedule, then this is an occasion to visit a doctor and find out what's the matter.

Often, parents believe that children have no roots and nerves on their teeth, since most often the child does not feel much pain when they fall out. He does not feel it if the tooth breaks out from the doctor, at a time when the extraction of a tooth in an adult can cause severe pain.

Milk teeth have everything, but the fact is that they tend to break down quickly, therefore, by the time they fall out, they are already very loose and fall out almost painlessly.

Mineralization of milk teeth begins during pregnancy, and their condition depends directly on the characteristics of its course. Further, during eruption, the crowns of milk teeth are filled with salts, the roots of milk teeth grow. Then, when growth stops, a certain calm period sets in, and then the roots begin to dissolve, and the milk teeth fall out.

A few years later, when the time comes to replace the milk teeth with permanent ones, the latter, as they grow, begin to push the milk teeth apart and provoke the destruction of the roots, as a result of which they easily loosen and fall out. If the tooth was treated, then it will fall out more difficult, sometimes there are times when it needs to be removed using painkillers, as when removing adult teeth.

In their structure, children's teeth are practically indistinguishable from permanent ones; they do not differ even in the number of roots. However, there is still a difference and they are as follows:

• the crown is smaller than the usual one;
• the roots diverge due to the rudiments of permanent teeth that are between them;
• enamel is thinner;
• the pulp in children is larger in volume;
• wide root canals.

Features of the eruption process

When the crown is fully formed, the tooth gradually moves from the place of its laying to the place of appearance, then, after eruption, it actively develops and grows. The dental tissues that are located next to it also change:

• the root develops;
• periodontium develops;
• there is a change in the tissues that cover the tooth;
• remodeling of the alveolar bone occurs.

After eruption, the crown grows further until it takes a position next to other teeth.

Teething is always considered one of the indicators of the correct and timely development of the child, an indicator of the health of the baby. Highly it is important that the teeth erupt on time, only slightly deviating from the accepted terms of appearance. The process of falling out of milk teeth and eruption of permanent teeth occurs simultaneously.

Milk teeth have a special structure, which can provoke the penetration of harmful microbes and toxins, which is why often eruption is accompanied by pulpitis, periodontitis or caries.

It is impossible to let this problem out of sight, referring to the fact that the teeth of children are about to fall out anyway. The fact is that the premature destruction of a milk tooth by caries can cause an abnormal development of the bite or jaw, therefore take care of your teeth and their hygiene whether they are temporary or not. They also help the child in the formation of speech function, the correct formulation of speech, as well as chewing food and its proper digestion.

So, as we have already mentioned, the appearance of the first tooth in a child at about six months is considered normal with minor deviations from the schedule. You can distinguish the imminent appearance of a tooth by the appearance of a mound in the gum area. So, pressure is applied to the gum mucosa from the side of the growing tooth. Then the shell begins to compress, becomes thinner and breaks under the pressure of the milk tooth. When his crown appears completely above the gum, this is considered the completion of eruption.

So, the first teeth of a child grow up to about the eighth or ninth month of life, but it is considered normal when they appear by the end of the first year. The roots of the incisors in children are finally formed around the end of the second year of life, the molars are formed by the age of four, and the canines by the age of five.

First, the child's central teeth erupt at the bottom, and then at the top right above them. After about a year they begin to cut side teeth, first at the top and then at the bottom. The appearance of the first molar usually occurs by the age of one and a half, and by two years the canines appear, after two - the second molars.

How many milk teeth should children have in total?

Most parents are often interested in how many first teeth should appear in children. So, by the age of two, a child usually grows up to 20 pieces:

• eight incisors;
• four fangs;
• eight molars.

Sometimes it happens that the teeth appear in the wrong direction, but usually by the age of three the entire dentition is formed and the child can actively chew food, while the teeth are in the right position.

A child's dentition should be fully formed by the age of three. Sometimes there are a number of deviations during eruption. These include the following:

• strong early or late onset;
• violation of the pairing of the appearance of incisors;
• occurrence determinism violation.

Sometimes there are cases when a child is already born with the lower central teeth. But their too late appearance indicates that the child is malnourished or often sick. It often happens that some milk teeth do not appear at all. This is because their rudiments died during pregnancy. There are also precedents for the appearance of extra teeth, which are awl-shaped and grow to the sides.

Timing of loss of milk teeth

The process of falling out of the first teeth and their subsequent replacement by permanent teeth begins at about five to six years of age. In most cases, the process of changing the milk teeth of the child does not disturb at all. Sometimes there are cases when a permanent one erupts, and the milk one does not want to fall out, then you have to remove them from the dentist.

The formation of a permanent dentition continues until about 14 years of age. Milk teeth change in the same order as they erupt. So, the incisors change from milk to permanent from about six to nine years old, the first molars - up to ten years, canines - up to eleven, and the second premolars appear last by the age of fourteen. If you do not keep a special account of the loss and growth of new teeth, it may seem that they grow less than milk ones. But it's not. As a rule, twenty of them fall out and then the same number grows, just the process of growth of permanent teeth, in comparison with milk ones, is too protracted and difficult to trace.

So, we found out how many milk teeth a child should have by the age of two - that's twenty teeth. Do not be discouraged if your baby has fewer teeth by a certain age than the neighboring children. If the deviation is not very significant, It's not a problem and sooner or later all the put teeth will still appear.

In all families where there are children, there comes a period of change of milk teeth to permanent ones. This process makes many people worry that everything goes smoothly. But in most children, tooth loss is tolerated without any problems.

Despite the fact that most parents are prepared for the change of teeth in children and are familiar with many nuances, there are cases of deviations from the norm. Teeth may fall out earlier or later than expected, inflammatory processes develop at the site of loss, new teeth erupt with curvature. Therefore, you should be very careful and, at the slightest suspicion of deviations, take the child to the dentist.

general information

Every person goes through natural process change of teeth. main reason Loss - preparation of a place in the oral cavity for permanent teeth, which will remain for life. Consequently, another logical question arises: why do permanent teeth not grow immediately?

The first teeth begin to erupt somewhere around 6 months. During this period, the baby switches from drinking milk or formula alone to more solid foods. But the child's jaw is still small, and does not contain the entire dental kit. The child grows up, and with it, his jaw also increases in size. The teeth remain in place, the interdental spaces increase between them, and the load on the teeth also increases.

By the age of 6-7 years, the foundation is laid for the growth of permanent teeth. The milk roots gradually dissolve, and the teeth begin to stagger and fall out, unable to stay in the hole.

Scheme of changing the dentition

The period of loss of milk teeth and the formation of permanent teeth lasts an average of 6 to 13-14 years. There is no clear order of change. It is impossible to determine which teeth a child will fall out first and which will be the last. The change is symmetrical. That is, the same teeth fall out on both sides of the jaw. In most children, these are the lower central incisors first, then the lateral incisors. Teeth in the upper jaw begin to change later.

Tooth change table

Lastly, the upper fangs erupt. And often there is not enough space for them in the already almost formed dentition. Therefore, they can shift, grow unevenly, overlap each other. The main orthodontic problems arise precisely because of the fangs.

It can take 5-8 years from the loss of the first milk tooth to the last one. How quickly this happens depends on many factors:

• gender of the child;
• mother's toxicosis during pregnancy;
• infections that the child had;
• the presence of chronic diseases;
• heredity;
• diet.

Symptoms

Before a milk tooth falls out, the child has the following symptoms:

• increase in interdental space;
• resorption of milk roots (when the process reaches the neck of the tooth, it is replaced);
• swelling of the gums, sometimes accompanied by pain;
• the temperature will rise to 38 ° C (in some cases);
• stool may be broken.

Note! Sometimes a permanent tooth may grow next to a milk tooth that cannot eject. In this case, it is necessary to remove the milk tooth, making room for the permanent one.

oral care

When changing teeth, it is important to properly care for the oral cavity. New teeth that have just appeared do not yet have the same strength as in adults, due to an unformed protective layer. Therefore, they need mandatory cleaning twice a day. Children are not very fond of any hygiene procedures. They need to be taught to use a toothbrush regularly, to explain to them the importance of cleanliness in the mouth.

Another important procedure that must be carried out before a tooth should fall out is the sanitation of the oral cavity. If there are signs on milk teeth, it can spread to permanent teeth. And since the enamel is still too weak in “young” teeth, they are very susceptible to damage.

Usually, when new teeth erupt, the gums have a rather loose structure and the child does not feel pain. But sometimes there are complaints about pain. To anesthetize the gums and normalize the microflora, local remedies are used:

• Kalgel;
• Dentokind;
• Solcoseryl;
• Kamistad.

After a tooth has fallen out, it is best not to let the child eat for 2 hours. Until the wound heals, it is better to refuse spicy, salty and very hot dishes. It is useful to feed the child with soups and cereals. Rinse your mouth thoroughly after eating. You can not remove the remnants of gore, they will fall out on their own in 2-3 days.

Sometimes the baby has a fever after falling out. If it general well-being fine, no reason to worry. If, in addition to temperature, there are other signs of malaise, this may indicate inflammatory process. The child needs to be seen by a dentist.

It is also important to monitor the correct formation of the dentition. If there are signs of misaligned teeth, the child should be taken to an orthodontist. During the growth of teeth, you can influence their position and form a beautiful smile in the future.

For better mineralization of young enamel, the dentist can carry out a procedure to strengthen the protective layer. In addition, you need to make sure that the child eats properly and receives the minerals and vitamins necessary for teeth.

Useful dairy products, greens, fish, vegetables and fruits.

Causes of too early tooth loss

Milk teeth hold space for permanent teeth and influence their future position. This is the so-called "spatial balance". Therefore, it is very important to save the first teeth until the permanent teeth appear. A free space is formed at the place of loss. Other teeth gradually begin to move towards it. And by the time when the time will come to grow a molar tooth, there is no room left for it; the tooth grows crookedly. To eliminate a defect in the dentition, you need to contact an orthodontist. He will install a special plate (“space holder”), which will prevent the displacement of the dentition.

Causes of early tooth loss:

• forced removal due to infection;
• trauma;
• malocclusion;
• extrusion by adjacent teeth.

Causes of Delayed Dropout

Sometimes even at the age of 25 there are cases when milk teeth are still preserved.

Various factors can influence the delay in the growth of molars:

• unbalanced diet;
• regular stressful situations;
• chronic infections (for example,);
• heredity.

If all milk teeth have not fallen out before the age of 17, a dental examination is necessary. This is a sign of a violation in the body, the cause of which needs to be found out.

Sometimes a milk tooth does not fall out, but only staggers. A permanent tooth has already grown nearby (“shark tooth”). No need to panic. After the baby tooth falls out, it will be installed in its place.

Permanent teeth can not grow for 2 reasons:

• Retention is a delay in growth. It can be complete (the developed tooth is completely in the gum) and partial (part of the tooth has erupted from the gum).
• Adentia - complete absence tooth. Occurs when a tooth germ dies.

For any defects in the dentition, a medical examination and treatment is required. In case of retention, a dissection of the gingival hood can be performed (provided that it develops correctly). These defects can be determined by the dentist after an X-ray of the jaws. If defects in the development of the dentition are detected, it may be necessary to install a temporary prosthesis, and subsequently a permanent one.

Change of teeth important period in life. At this time, the formation of teeth that will remain for life. From good nutrition, oral hygiene and regular visits to the dentist depends on the condition of the teeth in the future.
